Do I have to have the lipoma on my arm removed of its growing and how is the removal preformed step by step?

In brief:
Maybe

Normally small asymptomatic lipomas do not need to be removed other than for cosmetic reasons.

However if you have a lump under the skin that is tender, painful, or growing rapidly it should probably be removed and biopsied. Usually this can be done in an office setting with local anesthesia. An incision is made, the lump is identified and removed and then the skin is closed with sutures.

In brief:
Lipoma

Lipomas are for the most part benign collections of fatty cells.

They tend to be superficial so they can be removed using local anesthesia and simple excision. If they are small - it can be done in the office. The doctor numbs the skin and then makes an incision down to the level of the lipoma and "shells it out - closure is usually with sutures (stiches) or staples.
